How were the Northern Plains formed?
1. The Himalayan uplift out of the Tethys Sea and subsidence of the northern flank of the peninsular plateau resulted in the formation of a large basin.
2. In due course of time, this depression gradually got filled with deposition of sediments by the river flowing from the mountains in the north and peninsular plateau in the south.
3. A flat land of extensive alluvial deposits led to the formation of the northern plans of India.
